We have light-emitting diodes, light-emitting capacitors (EL wire), light-emitting resistors (incandescent bulbs), light-emitting vacuum tubes (CRTs among others), light-emitting gas discharge tubes (fluorescent lights, neon lights), but still no light-emitting inductors
this is clearly a very big gap and needs to be filled
@jk carbon nanotubes or magic, they're basically the same thing
